Jeep Cherokee (SJ): A Comprehensive Guide

The Jeep Cherokee (SJ) represents a significant chapter in Jeep's history, bridging the gap between the original Willys-Overland vehicles and the modern SUVs we know today. Produced from 1974 to 1983, the SJ Cherokee wasn't just a station wagon with Jeep styling; it was a capable off-roader and a stylish family vehicle that helped redefine the SUV market. It's considered a full-size SUV, offering ample space for passengers and cargo, combined with robust 4x4 capabilities.

Generations: A History of the SJ Cherokee

First Generation (1974-1983)

The first and only generation of the SJ Cherokee spanned a decade, experiencing numerous updates and improvements throughout its production run.

• 1974: The Cherokee debuted as a sporty, two-door variant of the Jeep Wagoneer (SJ). It was designed to appeal to a younger, more active market than the Wagoneer. Available engines included AMC's inline-six and V8 options.
• 1977: A four-door version was introduced, expanding the Cherokee's appeal to families. This broadened the Cherokee's market appeal and cemented its place as a versatile SUV.
• 1979: The Cherokee received a significant facelift, including a new grille and rectangular headlights, modernizing its appearance.
• Throughout the production run: Various trim levels were offered, ranging from the base model to the luxurious Chief and Laredo trims. These trim levels offered varying degrees of comfort, features, and styling enhancements. Engine options continued to evolve with improvements to fuel efficiency and performance.

Reliability & Common Issues

The SJ Cherokee, while robust, is a vehicle of its era and comes with certain reliability considerations. Understanding these potential issues is crucial for prospective buyers.

Engine Issues:

• AMC Engines: The AMC engines (inline-six and V8s) are generally reliable if properly maintained. However, oil leaks are common, especially in older engines. Regular oil changes and monitoring fluid levels are crucial.
• Cooling System: Overheating can be a problem, particularly with older cooling systems. Inspect the radiator, hoses, and water pump for leaks or deterioration. A thorough cooling system flush and replacement of worn components is recommended.
• Carburetion: Many SJ Cherokees came equipped with carburetors, which can be prone to issues such as fuel leaks, poor idling, and difficulty starting, especially in cold weather. A well-maintained carburetor or a conversion to fuel injection can improve reliability.

Transmission & Drivetrain:

• Transmissions: Both automatic and manual transmissions were available. Automatic transmissions can be prone to slippage or delayed shifting if not properly maintained. Manual transmissions are generally more robust but may require clutch replacement.
• Transfer Case: The Quadra-Trac full-time 4WD system (available on some models) is complex and can be prone to issues if neglected. Regular fluid changes are essential. Part-time 4WD systems are generally more reliable.
• Axles: Check for excessive play in the wheel bearings and signs of leaks from the axle seals. Regular lubrication is essential to prevent wear and tear.

Body & Frame:

• Rust: Rust is a major concern, especially in areas with harsh winters. Pay close attention to the floorboards, rocker panels, frame rails, and areas around the wheel wells. Thoroughly inspect the vehicle for rust before purchasing.
• Body Panels: Body panels can be difficult and expensive to source, so assess the condition of the sheet metal carefully.

Electrical System:

• Wiring: Old wiring can become brittle and prone to shorts. Check for damaged or frayed wiring, especially in the engine bay.
• Gauges: Gauges can be unreliable, so verify their accuracy.

Driving Experience

The SJ Cherokee offers a unique driving experience that blends rugged capability with classic SUV charm.

Pros:

• Off-Road Capability: The SJ Cherokee is highly capable off-road, thanks to its solid axles, robust 4WD system, and ample ground clearance.
• Spacious Interior: The interior is spacious and comfortable, offering plenty of room for passengers and cargo.
• Classic Styling: The SJ Cherokee's classic design is iconic and turns heads.
• Simplicity: Compared to modern vehicles, the SJ Cherokee is relatively simple to work on.

Cons:

• Fuel Economy: Fuel economy is poor, especially with the V8 engines.
• Handling: Handling is not as precise as modern SUVs. Body roll is noticeable in corners.
• Ride Quality: The ride can be stiff, especially on rough roads.
• Reliability Issues: As an older vehicle, the SJ Cherokee is prone to reliability issues.

Buying Advice

Buying an SJ Cherokee requires careful consideration and research. Here's some advice to help you make an informed decision:

What Years to Look For:

• 1977-1979 Four-Door Models: Offer the practicality of four doors combined with the updated styling of the late 70s.
• Later Models (1980-1983): May have benefited from some improvements in build quality and reliability, although rust is still a major concern.

What to Avoid:

• Rusted-Out Examples: Avoid vehicles with extensive rust, as repairs can be costly and challenging.
• Neglected Maintenance: Steer clear of vehicles with a history of neglected maintenance, as they are likely to have hidden problems.
• Modified Vehicles: Unless you know what you're looking for, avoid heavily modified vehicles, as the modifications may have been done improperly.

Key Things to Check:

• Rust: As mentioned earlier, rust is a major concern. Thoroughly inspect the vehicle for rust before purchasing.
• Engine Condition: Check for oil leaks, unusual noises, and signs of overheating.
• Transmission & Drivetrain: Test the transmission for smooth shifting and the 4WD system for proper engagement.
• Electrical System: Verify that all lights, gauges, and accessories are working properly.
• Paperwork: Review the vehicle's service records to get an idea of its maintenance history.

Ultimately, buying an SJ Cherokee is an investment in a piece of automotive history. With careful research and inspection, you can find a well-maintained example that will provide years of enjoyment.
